PREPARED ROOFING.

Application filed May 3, 1913.

To all whom it may concern.

Be it known that I, MATHIAS B. BECKER, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Prepared Roofing; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has for its object to provide prepared roofing of the character that is made in the factory and marketed in rolls ready to lay, which has its surface coated with grit of contrasting colors relatively arranged and disposed to form a predetermined pattern or design on the weather face of the material whereby it will be given an ornamental appearance similar, for example, to that of a tile or shingle roof.

Roofing embodyingmy invention is illus-.

trated in the accompanying drawings in which:

Figure 1 is a view in elevation of the weather face of roofing having contrasting grit coatings applied thereto whereby the v same is given an ornamental appearance. Fig. 2 is a fragmentary cross section of the same on the line 22 of Fig. -1. Fig. 3 is a fragmentary detail sectional view on an enlarged scale similar to Fig.

The commercial prepared roofing to which my invention relates is made in very large quantities and is very cheap, consisting of'a base or web of wool-felt, paperor other porous or fibrous material which is passed through a vat of boiling asphaltic material with which it becomes coated and impreg- The object of my present invention is to provide a roofing having on its surface a plurality of grit coatings of contrasting Specification of Letters Patent.

colors relatively arranged and disposed so that the contrasting colors will display a predetermined design or pattern on the roofing.

To this end I apply to the roofing after the primary coating of grit has been ap plied to its surface and upon and over said grit crating, a second coating -preferably of asphaltic material in pattern form so as to produce the desired design or pattern there on. This second coating is applied in liquid form in such quantity as to penetrate through the grit coating and upon the asphaltic base or coating holding said grit. Said second coating is of such a nature that it will amalgamate with and become inseparable from the lower coating. This is ac complished, preferably, in the manner and by the means fully described in Letters Patent No. 1,024,549 and No. 1,02at,550 issued to me on April 30, 1912. v

lVhile the pattern coating is still soft and fluent I project thereon in any suitable man-- ner, grit of any suitable nature and of a color contrasting with that of the primary grit coating and which becomes partially embedded in the pattern coating and is held thereby, any unapplied surplus of said lastnamed grit being shaken off and recovered in any suitable manner.

In the accompanying drawings which illustrate roofing embodying the invention as fully as the nature of the material admits, A indicates the porous or fibrous web and B and C the asphaltic coatings covering and impregnating said web. T o the coating B the grit particles are applied, the latter being of a uniform color and becoming partially embedded in said coating B and held thereby. The pattern coating E applied over and penetrating through the coat ing of grit particles D is shown to be homogeneo'us with the coating B and upon the same the grit particles F are applied which are of any suitable color contrasting sharply with the color of the particles D. The said particles F afford a protective coating for the pattern material and serve also to prevent the latter from adhering to the coating C when the roofing is rolled up ready for shipment.

I claim as my invention:

1. A ready-to-lay roofing comprising a base of water-proof material, and an ornamental protecting face formed of exposed Patented Oct. so, 1915.

diflerently colored grits relatively disposed at different elevations to present a desired design and intimately united with the baseto form a permanent part thereof.

2. A ready-to-lay roofing comprising a base of waterproofingmaterial having a surface of relatively raised and depressed portions bearing a protecting face formed of exposed grits, the grit on the raised portions differing in appearance from the grit in the depressed portions to present a predetermined symmetrical design, ultimately, united with the base to form-a permanent part thereof.

3. Prepared roofing comprising a Web coated and impregnated with a weather resisting material, the coating on one face of the web being varied in thickness in various parts or fields, a coating of granular grit of a uniform color partially embedded in the 'fieldsof least thickness and extending through and completely embedded in the parts or fields of greater thickness, and a coating of granular grit of a color contrastterial, and a suitable binder interposed therebetween.

5. A roofing material comprising a base having relatively thick and thin portions, the thicker portions having protecting grit -on its face and similar grit interposed betweenthe upper and lower surfaces of the base and completely embedded therein.

6. A roofing material comprising a base having relatively thick and thin portions, the thicker portions having protecting grit on its face and sides, and similar grit interposed between the upper and lower surfaces of the base and completely embedded therein.

7. A roofing material comprising a base having on its face relatively depressed portions, a layer of grit substantially exposed to protect the same, and relatively elevated portions similarly faced with grit substantially exposed to protect said elevated portions.

In testimony whereof I have signed my name in presence of two subscribing witnesses.
